Proposal: Provide guest access to anyone at all remote sites.
Reasoning: Guests need to have a distraction for long wait times

modem and route this traffic to an external connection over the same
link that provides internal VLAN traffic.
2. Build a separate infrastructure for wireless Guest traffic and
purchase a dedicated internet connection for all guest traffic per site.
